TREAD LE.

SPECIFICATION forming part of Letters Patent No. 645,466, dated March13, 1900. Application filed June 24, I899. Serial No. 721,760. (Nomodel.)

To all whom it may concern:

Be it known that I, NAPOLEON DU BRUL, a citizen of the United States ofAmerica, and a resident of Cincinnati, in the county of Hamilton andState of Ohio, have invented certain new and useful Improvements inTreadle Mechanisms, of which the followingis a specification.

My invention relates to a removable treadle mechanism and to meanswhereby the treadle mechanism can be suspended in elevated position awayfrom the floor to enable the washer, scrubber, or sweeper to readilyclean the part of the floor beneath the machineframe and at the sametime placing the treadle mechanism in convenient position for the machinist to Oil the bearings thereof.

My improved treadle mechanism comprises a pair of similarly-constructedright and left uprights or standards adapted to occupy a positionbetween the end frames of a machine and an upper brace-rod of the endframes and the floor on which the machine is set up and a treadle-platesupported by a brace or tie rod between the uprights or standards, eachup right or standard being constructed with a recessed upper end,providing lips or fingers adapted to receive and engage the upperbrace-rod and to enable the uprights or standards to act as stays forthe machine when in their normal position between the central brace-rodand the floor and provided with a hook'at its middle part, whereby thetreadle mechanism is suspended from the cen tral brace-rod when detachedand lifted up from the floor, as hereinafter described and v claimed.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which--Figure I is a front elevation of my improved treadle mechanism, showingit in connection with a part of a machine-frame and in normal position.Fig. II is an end elevation of the same. Fig. III is a vertical centralsection taken on the line III III, Fig. I, showing the treadle mechanismelevated.

The drawings show the lower parts of two end frames 1 of a machine,having feet 2 secured to a floor. by bolts 3.

4 are lower brace or tie rods having screw threaded reduced endsextending through the end frames and secured by nuts 5. 6 is an uppercentral brace or tie rod, also having screw-threaded reduced endsextending through the end frames and secured by nuts 7.

Between the end frames andbeneath the 7 upper brace rod is located myimproved treadle mechanism.

8 shows a pair of right and left uprights or standards similarlyconstructed, each formed with a base or foot piece 9, having inwardlyprojecting lugs or stops 1.0, with a transverse recess 11 and lips orfingers 12 at its upper end and with a recess 13'and hook 14 at themiddle portion of the upright or standard.

15 is a brace or tie rod having screw-threaded reduced ends extendingthrough the uprights and secured by nuts 16. This brace rod 15 supportsa treadle-plate 17, formed with pendent perforated ears 18, throughwhich the brace-rod 15 extends.

19 is a socket formed on the rear part of the treadle-plate to receivethe lower end of the operating-rod 20, which is hinged by a pintle 21within the socket. The pintle 21 is secured by nuts 22.

The uprights of the treadle mechanism being formed with recesses intheir upper ends enables them to be placed in a position between the endframes and beneath the upper brace-rod to fit against the latter andprovide stays bet-ween the upper brace-rod and the floor, whereby thetreadle mechanism is rigidly held and the machine-frame is strengthened,while the treadle mechanism can be readily withdrawn when it is desiredto suspend it from the upper brace-rod.

To remove the treadle mechanism and raise it, the upper parts of theuprights are grasped with the two hands and pulled from under the upperbrace-rod and the device is lifted up and hung by the hooks on the upperbrace-rod, where it is suspended or hangs pendent out of the way of thewasher, scrubber, or sweeper. When desired, the treadle mechanism can belifted off the upper brace-rod in the same manner and replaced in normalposition.

It will be observed that none of the parts of the treadle mechanism aredisarranged by the temporary elevation thereof.

- described.

2. A treadle mechanism comprising a pair f of uprights, means fordetachably connecting T them to a machine-frame, a downwardly-projectinghook near the middle part of each up- 1 5 right, whereby the treadlemechanism may be supported on an upper brace-rod of the machine-frame inan elevated position; substantially as described.

3. A treadle mechanism comprising a pair 20 of uprights, each havinglips at their upper ends, and a downwardly-projecting hook near itsmiddle part; substantially as described.
